Question

ILDUwn Browser + Webcam Most enzymes can be damaged, or denatured, by high temperature. Enzymes are not consumed in the reactions they catalyze. Question 11 (1 point) Which of the following statements are correct? Tyrosinase is an enzyme that forms hydrogen peroxide, a yellow-brown product. Catalase produces hydrogen peroxide from oxygen and water. If a sample of catalase is boiled we expect that it will not denature. Catalase is an enzyme Tyrosinase is an enzyme that requires oxygen as one of its substrates. Question 12 (1 point) DELL

Answer 1

Answer =

11.The correct statement are

Catalase is an enzyme

Explanation - Catalase is a common intracellular enzyme that breakdown the harmfull hydrogen peroxide into oxygen and water.

INCORRECT STATEMENTS :

Tyrosinase is an enzyme that forms hydrogen peroxide ,a yellow -brown product.- tyrosinase is a copper containing enzyme present in plant and animal tissues that catalyses the production of melanin and other pigments from tyrosine by oxidation.

Catalase produces hydrogen peroxide from oxygen and water - catalase that breakdown the harmfull hydrogen peroxide into oxygen and water.

If a sample of catalase is boiled we expect that it will not denature- -if a sample of catalase is boiled ,hydrogen bonds are loosen.and its structure gets denatured.

Tyrosinase is an enzyme that requires oxygen as one of its substrates - tyrosinase catalyses the production of melanin and other pigments by oxidation from the substrate tyrosine.the other substartes are tyrosine-betaxanthin and dopaxanthin.
